apply

The cfy apply command is used to install/update a deployment using Cloudify manager without having to manually go through the process of uploading a blueprint, creating a deployment, and executing a workflow. cfy apply command uses cfy install or cfy deployments update logic depending on the existence of the deployment referenced by DEPLOYMENT_ID.

It is recommended to read about cfy install and cfy deployments update in order to understand the cfy apply command.

cfy apply designed to improve blueprints development lifecycle. For example, during blueprint development and testing, it is useful to be able to quickly deploy and install the updated blueprint, overriding the existing deployment with the new changes.

cfy apply logic:

1. Check for BLUPRINT_PATH and DEPLOYMENT_ID.

2. If BLUPRINT_PATH is missing, use the default value and infer DEPLOYMENT_ID(explained in the usage section).

3. Check if deployment DEPLOYMENT_ID exists.

4. Upload blueprint BLUPRINT_PATH to the manager.

5. If deployment DEPLOYMENT_ID exists, perform a deployment update with the uploaded blueprint. Else, create a new deployment with the name DEPLOYMENT_ID, and execute the install workflow.

Usage

cfy apply [OPTIONS]

The cfy apply command uses the cfy install or cfy deployments update
depending on the existence of the deployment specified by DEPLOYMENT_ID.

If the deployment exists, the deployment will be updated with the given blueprint. Otherwise, the blueprint will be installed, and the deployment name will be DEPLOYMENT_ID. In both cases, the blueprint will be uploaded to the manager.

BLUEPRINT_PATH can be a:

• local blueprint yaml file.
• blueprint archive.
• URL to a blueprint archive.
• GitHub repo (organization/blueprint_repo[:tag/branch]).

Supported archive types are zip, tar, tar.gz, and tar.bz2

DEPLOYMENT_ID is the deployment’s id to install/update.

Default values:

If BLUEPRINT_PATH is not provided, the default blueprint path is ‘blueprint.yaml’ in the current working directory. If DEPLOYMENT_ID is not provided, it will be inferred from the BLUEPRINT_PATH in one of the following ways:

• If BLUEPRINT_PATH is a local file path, then DEPLOYMENT_ID will be the name of the blueprint directory.
• If BLUEPRINT_PATH is an archive and –blueprint-filename/-n option is not provided, then DEPLOYMENT_ID will be the name of the blueprint directory.
• If BLUEPRINT_PATH is an archive and –blueprint-filename/-n option is provided, then DEPLOYMENT_ID will be <blueprint directory name>.<blueprint_filename>.

Optional flags

This command supports the common CLI flags.

• -p, --blueprint-path PATH - The path to the application’s blueprint file. Can be a:
  • local blueprint yaml file
  • blueprint archive
  • url to a blueprint archive
  • github repo(organization/blueprint_repo[:tag/branch])

• -d, --deployment-id TEXT - The unique identifier for the deployment.

• -n, --blueprint-filename TEXT - The name of the archive’s main blueprint file. This is only relevant if uploading an archive.

• -b, --blueprint-id TEXT - The unique identifier for the blueprint.

• -i, --inputs TEXT - Inputs for the deployment (Can be provided as wildcard based paths (*.yaml, /my_inputs/, etc..) to YAML files, a JSON string or as ‘key1=value1;key2=value2’). This argument can be used multiple times.

• -r, --reinstall-list TEXT - Node instances ids to be reinstalled as part of deployment update. They will be reinstalled even if the flag –skip-reinstall has been supplied.

• -w, --workflow-id TEXT - The workflow to execute [default: None]

• --skip-install - Skip install lifecycle operations.

• --skip-uninstall - Skip uninstall lifecycle operations.

• --dont-skip-reinstall - Reinstall node-instances that their properties has been modified, as part of a deployment update. Node instances that were explicitly given to the reinstall list will be reinstalled too.

• --ignore-failure - Supply the parameter ignore_failure with the value true to the uninstall workflow.

• --install-first - In deployment update, perform install workflow and then uninstall workflow. default: uninstall and then install.

• --preview - Preview the deployment update, stating what changes will be made without actually applying any changes.

• --dont-update-plugins - Don’t update the plugins.

• -f, --force - Force running update in case a previous update on this deployment has failed to finish successfully [This option is deprecated].

• -l, --visibility TEXT - Defines who can see the resource, can be set to one of [‘private’, ‘tenant’, ‘global’] [default: tenant].

• --validate - Validate the blueprint first.

• --include-logs / --no-logs - Include logs in returned events [default:True].

• --json-output - Output events in a consumable JSON format.

• --manager TEXT- Connect to a specific manager by IP or host.

• --runtime-only-evaluation - If set, all intrinsic functions will only be evaluated at runtime, and no intrinsic functions will be evaluated at parse time(such as get_input, get_property).

• --auto-correct-types - If set, before creating plan for a new deployment, an attempt will be made to cast old inputs’ values to the valid types declared in blueprint.

• --reevaluate-active-statuses - If set, before attempting to update, the statuses of previous active update operations will be reevaluated based on relevant executions’ statuses. terminated executions will be mapped to successful updates, while failed and any *cancel* statuses will be mapped to failed.

• --skip-plugins-validation - Determines whether to validate if the required deployment plugins exist on the manager. If validation is skipped, plugins containing source URL will be installed from source.

• -p, --parameters TEXT - Parameters for the workflow (Can be provided as wildcard based paths (*.yaml, /my_inputs/, etc..) to YAML files, a JSON string or as ‘key1=value1;key2=value2’). This argument can be used multiple times.

• --allow-custom-parameters - Allow passing custom parameters (which were not defined in the workflow’s schema in the blueprint) to the execution.

• --blueprint-labels TEXT - labels list of the form :,:.

• --deployment-labels TEXT - labels list of the form :,:.
